We focus on the problem of distributing key updates in secure dynamic groups. Due to changes in group membership, the group controller needs to change and distribute the keys used...
This report describes a pay broadcasting system for the Internet. This system would enable tens of thousands of people to access an identical video stream simultaneously. In this ...
This paper puts forward new efficient constructions for public-key broadcast encryption that simultaneously enjoy the following properties: receivers are stateless; encryption is c...
We describe two new public key broadcast encryption systems for stateless receivers. Both systems are fully secure against any number of colluders. In our first construction both...
In this paper, we present a broadcast encryption scheme with efficient transmission cost under the log-key restriction. Given n users and r revoked users, our scheme has the trans...
